Craniamon is a Holy Knight Digimon whose names are derived from "cranium" or "cranial", and whose design is derived from the mythological Dullahan. It is the one that best understands decorum among the Royal Knights. It is a perfectionist, and competes with the other Royal Knights for the top two mission completion rates for Yggdrasill's orders. When fighting with an opponent, its policy is always to defeat it with one-on-one combat, and if the opponent is a formidable enemy, its delight is supreme. Craniamon's armor had its code modified by Yggdrasill, and was changed into Black Digizoid. It has become possible for it to generate its "Duo Solar Spear" (Claíomh Solais) and "Omni Shield" (Avalon) from its armor by accessing its data.[3]
